I use version 2.2 and recently had a hack on my page. I have removed the hack and successfully added the image verification scripts supplied above. Thankyou. I did not need to add the 2 amendments and it still worked ok.

I would be very interested to see a human verification system added aswell. My customer would like to be able to check the entries before they are submitted. Please let me know if there is now a mod available for this.
